JOHANN STU BER AND JACOB STUBER, OF SYRAUSE, NEW YORK.

BEER-COOLING APPARATUS.

'EBFECIFICATION forming part of Letters Patent No. 340,963, dated April 27, 188. Application filed October 28, 1985. Serial No 181,176. (No model.)

To a/ZZ whom it may concern:

Be it known that we, J oHANN STUBER and JACOB STUBER, of Syracuse, inthe county of Onondaga and State of New York, have invented certain new and useful Improvements in Beer-Cooling Apparatus; and we do hereby declare that the following is .a full, clear, and exact description thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference lnarked thereon, which forms part of this specitication.

This invention relates to apparatus and a freezing or refrigerati ng mixture used in conneet-ion therewith for cooling to the desired low temperature cellars and other rooms of build-V ings in which malt liquor is to be fermented or stored for preservation, or in which solid foods may also be stored for preservation.

The object ofthe invention is to provide a simple and economical means for producing and maintaining the desired low temperature in the fermenting and storing roolns.

The refrigerating mixture which we employ is the same as that used in our Patent No. 324,27 8, dated August ll., 1885, and contains as ingredients chloride of' sodium, chloride of ammonium, and chloride of calcium.

The apparatus used in forcing and circulating our refrigerating fluid, and forming part of our invention, is represented in the accompanying drawing, which illustrates the different parts partially in elevation and partially in perspective.

The cellar or room A is shown with its walls 'W in section, and 'with the refrigerating-coils M secured to the ceiling, while the fermenting tubs or vats L are ranged on the iioor. The sections of coils are connected with the inlet-pipe m, and with outletepipe n. The tank B contains the refrigerating solution to be circulated in the coils. The steam force-pump C, operated by engine H, connects by induction-pipe c with the bottom of the tank, and by eduction-pipe c with inlet-pipe m of the coils, and the return-pipe b leads from theoutlet-pipe n of the coils to the top of tank B. Steam-supply pipe d connects the dome of the boiler with the steamengine H. The tank B might be placed in the cellar to be cooled, while the pump, engine, and boiler should be placed in a separate room, all in convenient position for economical operation.

In operating the apparatus for cooling an apartment the tank B is charged with the refrigerating mixture of chloride of sodium, chloride of ammonium, chloride of calcium, broken ice, and a sufficient quantity of water, after which it may be closed. The pump is then started and the cold liquid forced through the coils ofthe pipe with a pressure of about fifty-ve pounds to the square'inch and returned to the tank to be again forced into the coils, and is thus circulated continuously or intermittently to the extent required for mailitai ning the low temperature required. At suitable intervals, as required, additional quantities of ref'rigerating compound and ice arecharged into the tank in order to keep the fluid sufficiently cold, and the surpluswarm fluid is periodically drawn off. The air in the top of the apartment becoming cool by the refrigerating'coils naturally falls, and a circulation is thus set up, whereby all parts of the apartment are uniformly cooled. y

rlhe apparatus as thus far described is the -same as that shown and described in our patent liereinbefore referred to, and we Will now proceed to describe the special objects and construction ofthe improvement We have made upon the same. 4

XVe have'found in practical operation ofthe device as hereinbefore described that the s0- lution in the tank B will deposit a sediment in the bottom thereof, which, if allowed to re main therein, will cake or crust into a solid mass and stop the circulation of the refrigerating mixture. To obviatc this difficulty, and at the same time improve the refrigerating eapacity of the mixture, is the object of this invention. ln carrying out these objects we provide an air-pump,.0, which may be operated by the engine H, or for which we may provide a separate engine, O', connected with 'the boiler and supplied with steam by means of pipe R. The pump draws air from the up per part of the tank B above the level of the mixture therein, and forces it through pipe Q into the tank near the bottom. #The pipe Q ends in the tank below the level ofthe solution,

IOO

and may be simply opened atits end,or may be provided with perforations, or may connect with a cross-pipe or a circular pipe Within and lying upon the bottom of the tank, and perforated so that the air will be discharged in all parts ofthe bottom of the tank,so that the mixture Will be kept in a constant state ofebullition, so that it will be impossible for the solids in suspension in the mixture to cake orcrust in the bottom of thetank. The air may, however, be drawn from any suitable supply by the pump and delivered,as before stated. This constant agitation of the mixture also serves to keep all parts ofit properly and thoroughly' mixed, and thus brings and keeps its refrigerating or cooling capacity at the maximum.

Having thus fully described our invention, what We claim as new, and desire to secure by Letters Patent of the United States, is-

In beer-coolers7 the combination, with the our 'own We hereto affix our signatures in presence of two witnesses.
